All mainline train services across south Wales have been suspended following a major power-outage at Cardiff.
The electrification failure has also caused delays to traffic after the level crossing at St Fagan’s jammed shut.
A spokesperson for Network Rail said that they were working with Western Power to get services back up and running.
“The railway in the Cardiff area is experiencing delays due to signalling failure caused by problems of power supply from Western Power.
“Our engineers are currently onsite and working alongside colleagues from Western Powers with an aim to bring services back up as soon as possible.
“Services travelling into and out of Cardiff are currently disrupted and passengers are advised to check their journey before they travel.”
The National Rail Enquiries website is reporting that all services through Cardiff Central have been suspended until further notice and that many trains may be delayed by up to 120 minutes.
